I had the same problem in Yosemite but thanks to this good soul based on these another good fellow I could solve it. I still can't understand what happened, but after losing a whole weekend trying to work it out I just gave up and blindly follow his instructions. Look at my desperation in activity monitor: Be careful, always do a backup first and read the ...

It sounds to me like your AC to USB charger is having a problem with heat. It charges for a while (while heating up) then it stops. If you let it cool down for a while I assume it continues charging. In any case, I would suggest replacing it.

It happens to me on my MBA, no charging light on. By moving the mag connector (like let it snap in few times) it then comes up. Just a bad connection. You can try cleaning it with alcohol. And I also have the "Service battery" but that is only a recommendation. Next level would be displaying "Replace soon, or Replace Now. While the light on the ...

You can use the battery from the phone that is not from your provider, but not switch radios. Batteries between models, e.g., iPhone 5, are the same even when the radios are not. Even when radio types are the same, e.g., GSM vs GSM, the operating frequencies, etc., often aren't. Other pieces, such as screen glass, case, screen layers and the like are also ...

To determine the Battery status open About this Mac -More -System now look for battery information in there under Power. Look for: Charge cycles count < 600 for yours and the Full Charge Capacity (mAh): > 4557 In any case resetting your SMC (System Management Controller will help some).

In order for cables to smoke the current must have exceeded all limits of the design by 10x. Since the battery is connected true it, it would have gotten a shock of its life, and now no longer been able to hold the charge. The guy at Best Buy was right, it is not the cable any more since the damage was done.

Yes, it's fine to leave it plugged in. The charger is simply disconnected and there is no closed circuit.

I am using a 13-inch mid 2014 MacBook Pro with Retina Display. It is about 3 weeks old and already has clocked 13 charge cycles. Is this too high? A charge cycle is just the process of using and then recharging the full capacity of the battery one time. From Apple: A charge cycle means using all of the battery’s power, but that doesn’t ...

I have asked Apple. The Apple tech support gives me these recommendations : When the charging is done, unplug the iPad. Once a month, do a full cycle : full discharge then full recharge. Otherwise, plug and unplug the iPad as you like, full cycles are not needed.

I have had the same problem occur to me after a completely new battery was installed in a MacBook Air from late 2011. From 100% I woke up the next day to find the battery at 28%. So I dug up some research I had done and it comes to this command: sudo pmset -a hibernatemode 25 From examining your setting I see yours is not 25 but 3, if you have not found a ...

I have a 2012 MBA as well. The battery is still doing it, at 510 cycles now. In your case try the SMC reset to fix that problem. If you hold the "alt" key then click on the battery, it will give you some information including what is consuming it. If you open the Activity Monitor in your Utility folder, then click on the Energy tab, there will be a ...

It doesn't really matter. You're already using up some capacity when you charge past 50%. For long term storage, Apple recommends that you only charge the device up to 50% and then power it off. Basically if you are concerned about the longest capacity of your battery, you wouldn't consume it at all and you'd just charge it to 50% and then put it in a box ...

Safari actually uses less energy than crime or Firefox but it honestly depends on the website open and number of tabs

Yes, turning off WiFi will save power. In case you are not using any data it will but if you still gonna use cellular data with Wi-Fi off then it might be that you actually get less of battery life since data on cellular uses more battery than on WiFi especially if signal is weak. For example for iPhone 6 (for 5 it was about the same) specs for Power and ...

Battery box or battery health. You could also contact Apple for a diagnostics test (they will text or email it to your iDevice)

Every developer at our company uses a 15" retina MBP (16GB RAM) as a desktop. They're fantastic, and the battery doesn't suffer noticeably. Several of us run two external monitors as well. At night we close the lids and put them in a secure room. The only drawback is network share drives, which seem to need reconnecting each morning, which is a pain if ...

You really hasn't stated you workflow but here is my thought: The main disadvantage to me in this scenario is total cost by which I understand less powerful CPU/smaller screen for more money and also higher risk of getting into problems with GPU since it is the most failure prone component in notebooks as we see for years. And don't forget that a cup of ...

When a phone shuts down at voltage levels that show 30 to 80% charge, it's almost always a faulty portion of the battery that causes the voltage to drop precipitously. The other reason would be a loose connection, so if you want to re-check your work, that would be good to focus on. I would expect the device to be much more flakey or you can rule out a bad ...

Few ideas: Have you tried a full blown factory restore? Are you SURE everything internally on your phone is secured and exactly as it was when you first opened it? Might be worth it to open it up again and double check. Have you contacted the battery seller? I've personally never heard of 'em, but then again I've never been in the market for a new iPhone ...

You are either shorted something while replacing the battery or battery is a dud. That happens sometime. And since Duracell direct has nothing to do with Duracell brand of batteries it probably a dud. Since it is not possible to get original one except from Apple service buy either few of cheapest or one of brand name compatible batteries that don't pose ...

I woke up yesterday morning to this article in my newsfeed: http://www.businessinsider.com/man-fixes-laptop-by-putting-it-in-the-oven-2014-12 When we replaced the first logic board, I had found that this is a widespread problem and people are trying to get Apple to address it. ...
